Why Lachen Was Closed?
Lachen’s road connectivity – particularly the Chungthang–Lachen stretch near the Rabam Chu and Taram Chu rivers – has faced repeated damage since the 2023 glacial lake outburst flood (GLOF), with further monsoon landslides disrupting the route through 2024, 2025, and again in 2026. The Border Roads Organisation (BRO) and Sikkim PWD have carried out phased restoration, and Lachen has typically reopened each year once the monsoon season ends – a pattern this September 2026 reopening follows.
What You Can Visit Once Lachen Reopens
• Lachen village – the last inhabited settlement before the high Himalayas, home to the historic Lachen Monastery
• Gurudongmar Lake – a sacred glacial lake at over 17,000 ft, revered by Buddhists, Hindus, and Sikhs
• Thangu Valley – an alpine meadow ideal for acclimatisation before the Gurudongmar climb
• Chopta Valley – an offbeat, less-crowded high-altitude stop near Thangu
North Sikkim Permit Rules for Lachen (2026)
Lachen falls under a Restricted Area, so a special Inner Line/Protected Area Permit is mandatory for every traveller – Indian and foreign.
• Permits must be applied for at least one day in advance; same-day permits are not issued
• Applications go through a registered tour operator only – individual/independent applications aren’t accepted for this sector
• Original photo ID and passport-size photographs are required
• Vehicles must cross designated checkpoints (e.g., Toong, Sanklang bridge) before fixed cut-off times, typically early afternoon
• Foreign nationals face additional restrictions and may need special clearance for Gurudongmar Lake specifically
Yakrong Trips is a government-registered tour operator (Reg. No. 1701/DoT&CAv/GTK/25/TA) based in Gangtok, and we handle the entire Lachen permit process – no paperwork stress, no rejected applications at the checkpost.
How Much Does a Lachen–Gurudongmar Lake Tour Cost?
A typical North Sikkim tour package including Lachen ranges from ₹8,000–₹20,000 per person for a 3–4 day trip from Gangtok, covering vehicle, accommodation, meals, and permit processing. Costs vary by group size, hotel category, and whether Lachung/Yumthang Valley is combined into the same itinerary — which most travellers do, since it’s a more efficient use of permits and travel days.
Best Time to Visit Lachen After the September 2026 Reopening
Late September through November brings the clearest post-monsoon skies and most stable roads of the year – arguably the best window before winter snow makes the Gurudongmar route unpredictable (December–February). If you’ve been waiting for the right moment to book, this reopening window is it.
Is It Safe to Travel to Lachen Right Now?
The route reopens only after official clearance from the Mangan district administration and BRO, and thousands of tourists have made the trip safely during past reopening windows. That said, North Sikkim terrain remains landslide-prone during unstable weather, so we recommend travelling with a registered operator who tracks real-time road status – not just going by an app.
